SAFETY-GUN.

gagement of the hammer with the pin in the event the hammer isaccidentally actuated or released, and to emplo a means in connectiontherewith operab e to shift the said means to permit firing.

An important object is to provide a gun with the means to prevent4accidental firing and which' is opera-ble to permit firing byvengagement with the shoulder of the gunner or operator and thus operateautomatically during the act of positioning the gun.

vWith the above and additional objects, such as will hereinafter appearin'detail, the invention has been embodied in Vone preferred form4 asillustrated in the accom.- panying drawings, wherein Figure 1 is afragmentary view of a gun shown mostl in section at the stock, andprovided wit my improvements,

Fig. 2 is a'view showing my improvements in top or plan view,

Fig. 3 is a cross sectional view -on the line 3-3 of Fig. l, and.

Fig. 4 is a detail perspective of the cam l comprising theguard-shifting means.

Referrino` to the drawings, wherein like reference c aracters designatelike or simi-` lar parts, a gun is shown fragmentarily but merely by wayof example since the specific construction is immaterial as far as mimprovements are concerned. The gun s own has a suitable stock at 10provided with the usual pivoted hammer 11 adapted to engage a 'rin pin12 disposedas usual at the rear of the arrel 18. A guard 14 is providedfor normal disposition intermediate the hammer 11 and the firing pin 12,that is the guard projects beyond the exposed end ofthe firing pintowardthe hammer, so-'that'if the hammeris accidentally released, itwill engage the guard 14 but will not engage the firing pin 12 andaccordingly will notfire the car- Speciication of Letters Patent.

tridgelor charge. This guard 14 may be of any suitable construction, forinstance an arm which is vertically disposed in a guide 15 of anysuitable construction. If desired the guide may be dispensed with andthe stocl 10 cut away to provide a substantially longitudinally disposedhollow or space at 16 within which mostiof the parts for actuating theguard 14. are disposed. A fulcrum 17 extends .transversely of the stockand has l mounted thereon a lever 18 which is pivoted by means of thepin 20 to the guard 14:. This lever is normally main-tained raised atits forward end, so that the guard 14 will be in guarding position, bymeans of a spring 21 which engages and surrounds a lu provided'on lever18 and a lug 23 provided on a plug 24 screwed, as shown, into the stock10. A lug or shoulder 18 onlever' 18 limits the rearward pivotalmovement of the uard and maintains it in a vertical position.

'his guard at the forward end is contiguous to the rear Aend of barrel13 and it extends backward beyond the exposed end of the firing pin soas to be in the p ath of movement of the hammer before striking the pin.

AIt will thus be seen that I have rovided a means which will revent`acci ental dis# charge of the cartri ge '0r load and thus the arm may behandled with absolute safety.

A suitable means is provided to shift the guard in order that the hammer1 1 may engage the firing pin 12 at thel desired time.

Any suitable means may be employed, but l:`

preferably employ a cam 25 w ch rests on a flat wall 26 in the hollow16. This cam has an inclined or cam wall 27 which the rear end of thelever 18 en ages so that 'as the cam is moved toward the ammer, it willtilt the lever 18, raising the rear end and lowering the front end andmoving the guard 14 out of the path of movement of the hammer-11. Cam-25may be fastened to a rod 28 disposed .in the hollow 16 and extendingfrom push block or button 29 also mounted inhollow 16. A Lplate 30 isanchored to the stock and dispose in the hollow 16 and the rod 28`slides therethrough havinga crank or angle 31 to abut the plate and mitthe outward movement of the rod. A coil expansion spring 32 surroundsthe rod 28 intermediate the plate 30 and the block 29, bearing againstthe same and serving to normally roj ect the push block beyond the buttend o `the stock and the crank 31into engagement .with the plate 30.AInward movement 'of the ,pusb

-. merA automatically during positioning of the block 29 is limited bythe wall 33 of the stock f at the hollow. l It is important that thepush block 29 should extend beyond the butt end since it forms a'construction whereby the guard is moved out of the path of the hamgunfor firing. v In use, the gunner the stock at the butt end against theshoulder. However, during such movement, the

` push block 29 first engages the shoulder and it is moved as a resultinteriorly of the stock, that 'is Within .the hollow 16. As a result,the rod 28 and cam 25 are pushed toward the hammer against the tensionof spring 32, raising the lever 18 at itsrear end against the tension ofspring 21 and lowering the l guard 14v out of the path of movement ofthe hammer 11. These parts will remain in this position while the gunstock at the butt end is held against the shoulder and while they are insuch position, the firing may be' effected. As soon as the gun is movedaway from the shoulder, the spring 32 will force the block 29 outwardlyand spring 21 will force the lever 18`and guard 14 into normal Ivpositions whereby the latter is in the path of movement of the hammer.-A

Since merely the preferred embodiment of the invention has beenillustrated and described, it is to be understood that changes in thedetails of. construction ma be resorted `to without departing from t espirit and scope of the invention.
